10 Claims. ((1101-93) 1 This case is a division of my copending application Serial No. 725,837, filed May 16, 1934.

The present invention relates to improvements in fraction printing devices and more particularly is concerned with perforated record card controlled apparatus which is adapted to receive entries. of debit and credit amounts in English currency and to list a printed record thereof.

An object of the invention is to provide an improved means for printing debitand credit amounts in the duo-decimal system, such as pence, twelfths, inches, dozens, etc.

A feature of the invention is the improved devices for using a standard Hollerith type of record card for controlling the printing of positive or negative fractions and English currency amounts.

Another object of the invention is to provide means for controlling the printing of a multidenominational ordered number by means of a special perforation on a record card.

An object of the invention is to provide means for sensing a special perforation representing a multi-denominational ordered number on one cycle of the machine, and then causing printing of such a number on the following cycle of the machine.

An object of the invention is the provision of devices for entering and printing complements of a multi+denominational number represented by a single perforation on a record.

Another object of the invention is the provision of printing control devices adapted for universal use in the decimal system, for fractional representation and English currency tabulation.

A feature of the invention is the selective control of two typebars by a single column of perforation positions on a card or a single position on an accumulator wheel. The printing of a single decimal digit by one bar or the printing of duodecimal figures by two bars represents either an entered item or a total.

Further objects, uses, and advantages of the present invention are pointeii out hereinafter in the specification and claims and shown in the drawings which illustrate what is considered to be the preferred embodiment of the invention.

In the drawings: Fig. 1 is a side elevationalview of the machine showing the driving and operating connections.

- Fig. 2 is a vertical section taken through the center of the machine.

Fig. 3 is a detail view of a portion of the perforated record card used to control the machine.

Fig. 4 is a portion of a record strip showing the recording of a few amounts and a total.

,represent two amounts in English money.

Figs. 5A and 53, when taken together, form a wiring diagram of the machine.

Referring to the portion of the card I disclosed in Fig. 3, a plurality of columns of index point positions ranging from R to 9 are shown. An amount which is to be added or subtracted in a machine is entered by perforations in the succes-.

sive columns.

perforation 2 shows that the amounts on the record are credit items. The amounts are punched in the same manner to indicate either a credit item or a debit item. If the card contains a credit item, the control perforation 2 is punched in the upper portion of the card and used to control the machine to effect reverse operation of adding and subtracting in the accumulators of the machine. In the absence of such a perm-- ration, the machine will effect addition of a true number in a debit accumulator and add the complement of the true number in the credit accumulator.

In Fig. 3, the perforation 2 is shown in the twelfth'colunm of index points on the card. The

perforation may be placed in any of the columns and the machine may be plugged accordingly.

The cards are fed through the machine by feed rollers and analyzed successively by upper sensing brushes UB and lower sensing brushes L3 in the usual way. The card is fed past the brushes with the 9 index point position passing under the brushes first, followed by the 8 position, and then the 7, and so on in a manner which is well known in the art.

The upper brushes are used for control sensing while the lower brushes effect the adding and subtracting of the amounts represented on the card. When an item on the card is to be added in one of the accumulators and a perforation appears in the first column in the 6 index position (as in Fig. 3) then when the perforation passes under the lower brush the related accumulator wheel is clutched to the driving means to commence adding one unit as each of the succeeding points on the 1 its.

- so that it stopsturning. It will thus have turned six steps to accumulate thevaluefi. In the fourth column on the card, the related lower brush will contact with the perforation the X position to 5 clutch the related accumulator wheel to com-' mence adding one step before the nine position on the following cycle of the reading in the card. Then, when the zero position is reached and the wheel is declutched, the value will have been 10 added.

During the entry of a credit item, the described adding operation takes place in the credit accumulator. The machine may be arrangedso that as this is occurring, a debit accumulator may be controlled so as to enter the complement of the number added in the credit accumulator. In order that an accumulator may receive the complemental amount, its accumulator wheels are clutched early in the cycle so as to commence adding in 0 all orders except the units order when 'the 9 index point position on the card passes under the lower brushes. The units order or pence wheel is clutched three steps before the other wheels. When a perforation is sensed by the lower brush in any particular column, the accumulator wheel in the credit accumulator is declutched. Another form of mechanism is provided to take care of the entry of complements in the pence orders. This mechanism is operated to enter the value 1 or? according to whether -11 or 10 pence perforations are presented in the pence order columns of index points.

,In the order representing tens of shillings .or

wheel takes place in the index point 'I and is adapted to cause the entry of either one or zero according to whether the index points zero or one are punched in the card. In this way the comple ment of any possible number of shillings ranging up to 19 may be entered in the tens and hundreds wheel representing units and tens of shillings.

When a perforation issensed by' the lower brushes in any of the columns other than the pence or shillings columns, the related accumutor wheel associated with the first column will commence adding as the nine position passes the related lower brush and then as the 6 position passes the brush the perforation in this position will be sensed and the energization of an electromagnet will cause the accumulator wheel to be disengaged after entering the amount 3" which is the complement of the figure 6. represented on the card. Since no perforations appear in the next two columns on the card, the complement 19 will be entered into these two accumulator wheels.

. The fourth column is perforated to represent the: value '10' andjtherefore the jsjengered order since the-.Values 2 and 10. are {complementarydnthe 5 The printing meehanism'lncludes a platen 22 (F113; 2);and'a series of type carriers lleachhav Fingi a plurality of type elements 94 adapted to be struck by a hammer 95 loosely pivoted ona shaft The typecarrier isoonnwi at its lower end 9'! fulcrumedat I 98 39 7 8 98 con-'- 'nectedto firearms flandito across beam Ill can nected-between a'rms m pivoted at m, tend to raise the arms 91 to raise the type carriers.

An arm I05 (Fig. 1) fixed to the shaft I02 on which the arms III arealso fixed, is connected by a link I" to a complementary cam follower arm III'I pivoted at Ill and cooperating with cams I09 and Don cam shaft I I I.

Shaft I I I,is driven through achain of gears I I2,

H3, and H4 the latter of which is mounted on a perforation in the card at the nine position, a

circuit will be closed through the brush LB to a printing magnet PM (Fig. 2) of that particular column. This will attract the associated armature II5 which is connected to one of the rods IIS which at the other end is connected to a latching member II! of that particular column. This will release a latching pawl Illpermitting it to cooperate with the top one of the ratchet teeth II! carried by the type carrier'to stop the type carrier with the nine type 94 in line for printing.

When the arms m raisethe bail m to permit I the type carriers to rise, the springs "will be stretched when'the type carriers are latched and the arms 91 are stopped in differential positions.

- After printing has been effected, the arms I ll are then lowered with the bail III to restore the type carriers to normal position.

The latching pawls Ill must then be restored before the type bars can begin the next upward movement.- For this purpose a bail I2! is adapted, when rocked clockwise, to rock the latching pawls III counterclockwise against the action of their spring and permitthem to be latched by the latches III. The ball I2II is connected by a link I2-I to arm I22 fixed on shaft-I23 on which is also fixed an arm I24 (Fig. 1) connected by link I25= to an arm I26 pivoted'at I21 and connected to a cam follower arm I28 (Fig. 2) adapted to be actuated byacam I29 on shaft III.

Where listing is to be eflected on a record sheet I40 (Fig. 4) ,while an item is also being accumulated, the printing magnet PM will be connected to receive an impulse through the perforation in 5 the card simultaneously with the transmission of such impulse to the related accumulator magnet AP, A or AH. The amount may be listed whether the item is a debit or a credit.

The total taking control When a total is to be taken of a group of items which have beenaccumulated, and the total or I balance is to be printed, it is necessary to open -the listingv circuits to the sensing brushes and close the total printing circuits to contacts in the accumulator. The mechanism for effecting these circuit changes is controlled by a total control magnet TM, the operation of which is explained with reference to the wiring diagram. This magnet is adapted to be energized either by depression of the total key or automatic operation of group control devices whenever a total is to be taken.

The plugboard circuit breaker switch During accumulating, total taking and transferring operations it is necessary to break connections between the sensing brushes, the accumulator magnets and the total printing contacts in order to prevent back circuits. v

The devices .for opening and closing the contacts PBCA and PBCB (Fig. 5B) are shown in Fig. 2. A plate I85 is fastened tothe machine frame near the card feed control shaft I54. The plate carries a series of contacts arranged in groups of three, an upper blade I96, a center blade I81, and a lower blade I88. Each center blade I81 projects into a slot I89 cut in the side of a vertical insulation bar I90 riveted on a link I9I.

-A bell crank I92 pivoted at I93 is pivotally connected to the link I9I at I94, and on the end of a vertical arm carries a roller I95 cooperating with a cam I 96 on shaft I54. Another horizontal arm (not shown) guides the lower end of link I9I.

5 The cam I96 has three different concentric levels I91, I98 and I99 for adjusting crank I92 and controlling the contacts.

Early in the counterclockwise movement of cam I 96, the roller is raised to level I91 and the crank is rocked counterclockwise to close the upper contacts PBCA and condition the machine for adding so that the impulses from the lower brushes are directed to the accumulator magnets. At transferring time, the crank roller I95 falls to level I98 and closes the lower contacts PBCB en-' abling the transmission of transferring impulses through the transfer contacts to the accumulator magnets. Then finally the crank is brought to rest on level I99 whereupon both contacts PBCA and PBCB are opened and the machine is adapted to take a total.

The machine operating connections on the card appear under the upper and lower brushes UB and LB.

When the start key is depressed, contacts 203 are closed and a circuit Is established from line 200, through the stop key contacts 2I6, contacts MII card feed clutch magnet CFCM, magnet R6 in parallel therewith, contacts 203 and wire 204 to'line 20I.

The energization of magnet CFCM will cause operation of the card feeding mechanism to feed cards through the machine. This magnet also controls contacts CFCI andCFC2, closing them when the magnet is energized. As the cards feed through the machine they depress the lower card lever and operate the lower card lever contacts LCL. The magnet R6 closes contacts B6B as long as cards are feeding, but opens these contacts to prevent the passage of pence accumulating and printing impulses during the taking of a total.

When contacts LCL are closed a circuit is established through magnets CLR and CLRH, from line 200, through contacts LCL, magnets CLR, CLRH, in parallel, and wire 205 to line 20I. The

magnet CLRH when energized forms a holding,

circuit by closing contacts CLI which are in series with contacts CR2 which close when contacts LCL open. The other magnet CLR closes contacts 0L4 in parallel with start key contacts 203, so that by means of contacts CFCI and GL4 the energization of magnet CFCM is maintained after the start key is released. If the auto start switch AS is closed as shown, the closing of the contacts PI at the end of a total cycle serves to energize the magnet CFCM and resume card feeding. If cards fail to feed because of an empty magazine or jammed cards, the contacts LCL remain open and the circuit is opened at GL4, deenergizing the card feed clutch magnet and stopping the card feeding mechanism.

If printing is to be effected under control of the cards being fed through the machine, the list switch'is closed as shown so that when contacts CF02 are closed by magnet CFCM and contacts GL3 are closed by magnet CRL, the printing clutch magnet PCM is energized. The circuit is as follows: line 200, wire 206, magnet PCM, wire 201', contacts PCI, contacts CFC2, contacts M15, the

switch arm, contacts GL3; and wire 208 to line 20I.

The energization of magnet PCM causes the printing operation devices to be clutched to the main operating mechanism so that the type bars and associated mechanism are operated. If tabulating control of printing is desired, the switch may be shifted to TAB, then during the printing of the first card after a total, contacts P2 open to deenergize magnet PCM. The magnet remains deenergized during the accumulation of a group of cards because contacts'PCI are opened by the unlatching' of armature 209 by energization of magnet PCRM. The circuit includes line 200, contacts CL2 closed by magnet CLRH, contacts CF2, contacts P3 closed during the printing of the first card after the total, magnet PCRM, the switch arm at TAB, contacts CL3 and wire 208 to. line 20I.

The magnet PCM may be energized for the printing of a total by the automatic closing of contacts M12, 'or the closing of contacts 2 by the hand total key. The circuit is from line 200, wire 206, magnet PCM, wire 2I2, contacts MI2, wire 2I3, the switch HTS in the position shown for automatic totals or moved to the left for hand totals, thence through wire 2I5 on' contacts 2| I, contacts CR3 normally closed, and wire 320 to line 20I.

While the machine is in operation and cards are being fed the machine may be stopped at 5 any time by depression of the stop key to open the contacts 2I5. This will break the circuit through the card feed clutch magnet CFCM which then allows contacts CF02 to open to deenergize the printing clutch magnet PCM. The operating motor will continue to operate until the switch at PS is opened.

A platen feed mechanism isprovided to feed the record paperbefore printing in both listing and total taking operations. A platen feed magnet PFM, when energized acts to clutch the platen spacer to the driving mechanism. The circuit through the platen feed magnet is as follows: line 200, wire 2I0, switch SF, contacts CFI I, contacts P4 closed during printing, paper feed magnet PFM, and wire 2 I4 to the other line MI. The magnet may be energized in automatic total taking by the closing of contacts M13 and contacts P5.

The passage of cards under the upper brushes UB serves to deenergize magnets RI and R2 which in turn control the operation of many contacts throughout the machine. These contacts are associated with magnet R2 and are operated thereby to indicate the presence of cards under brushes UB. When cards fail to appear under the brushes UB a circuit is closed through line 202, wire 2I5, common brush 230, contact roller 23I. brush 219, contacts CFII, magnets RI and R2 in parallel and wire 250 to line 200. Magnet RI closes associated contacts RIA and a holding circuit is established through contacts CF5 and RIA.

In an ordinary adding operation, as the card passes the lower brushes LB the amount perforated therein is added and printed. The circuit 40 is from line 200' (Fig. 5A) contacts GL2, wire 245,

contacts CF2, common brush 2I5, contact roller 220, brush LB touching roller 220 at a differential time controlled by the location of the perforation, jack 22I,'plug wires to jacks 224 and 25I 45 if both adding and listing control is desired;

then the circuit branches out in two parallel circuits, the printing or listing branch includes contacts I14, printing magnet PM and line 202; the adding branch continues through jack 224, cable 50 225, (Fig. 5B), contacts'41B closed foradding,

wire 350, contacts PBCA closed during accumulating, wires 35I and 352, contacts I14 closed for item entry, accumulator magnet A and line 202.

The energization of the accumulator magnet 55 acts to clutch the accumulator wheel to the driving gear and rotation continues until cam 5I (Fig. '7) declutche's the gears.

The addition of the amounts 1 to 9 are carried out in a similar way in the pence order.. The

60 circuit for the addition of such numbers in this lower order bank may be traced at the top of Fig. 5B. The impulses from the lower brushes travel along the cable 225, through wire 353, contacts' PBCA, wire 354, contacts 355, wire 355, 65 contacts 351, wire 350, contacts 353 closed during adding, wire 350,. wire 352, contacts I14, magnet AP and line 202. a

The listing of the ordinary decimal figures in the pence order follow a path somewhat different 7 from the printing circuit in the higher orders. The circuit may be followed in Fig. A from line 200, contacts GL2, wire 245, contacts CF2, common brush 219, contact roller 220, brush LB in the lower order, jack 22I, a plug .wire to socket 75 224, wire 35I, contacts 352, plug socket 353,-a

. and magnet RI55 and wire 31I to line 20I.

Plus wire to socket "I, in the pence order of printing bank, contacts "4, magnet PM and line 202. v

In the adding of ten or eleven pence in the lowest order of the accumulator a different mode of entry is employed. The perforations mepresenting these two amounts are placed at the top of the column of index points on-the record card I. Referring to Fig. 3, it is noted for the perforation in the fourth column from the left that the X position represents pence. A perforation in the 9th column at the R index posi-' tion represents 11 pence. These two perforations aresensed as the card passes through the upper brushes, one card cycle before the regular adding operation takesplace as the card passes through the lower brushes. The sensing of such perforations causes contacts to be adjusted for the early meshing of the accumulator wheels to addthe amount-10 or 11.

Considering first the mode of operation for the entry of 10'p'ence, the sensing of an X perforation in the pence'column setsup a control circuit which may be traced starting with line 202 (Fig. 5A) through wire 2.", common brush 230, contact roller 23I, brush UB in the lowest order,

socket 232, a plug wire tosocket 233, magnet RIO, wire 354, brushes 355 which make contact with a segment 355 on a commutator 351 which is rotated in synchronism with the feeding of the card and adjusted to make contact as the X position passes the upper brushes. continues through brush 355 contacting a continuous ring on commutator, contacts CF5,contacts R2A and line 200. The energized magnet RIO closes contacts RIOA and sets up a holding circuit including magnet RI55. The circuit may be followed from line 200, wire 353, contacts CFII, wire 310, contacts RIIIA, holding magnet RIOI-I- energized magnet RI55 holds contacts 351 opened The circuit Theand contacts 312 closed during the following cycle a to add 10 pence into the accumulator. I The circuit through accumulator magnet AP for the addition of 10 pencejmay be followed from line 202 (Fig. 5B) magnet AP, 'contacts I14, wire,

352, wire 350, contacts 359, wire 355, contacts 312 operated by magnet RI55, wire 313, brush I 0A cooperating with a commutator 314 provided with a spot .315, contacting brush IIIA, early in the adding operation at the time calculated to mesh .the accumulator wheelto add the value 10. The circuit'continues through spot 315 to a contact ring 315, common brush CA, contacts R53. wire 311 (Fig. 5A),wwire 315, wire 245, and contacts CL2 to line 250.

During the adding of the 10 pence inthe lowest order of the accumulator, the number ten is printed on the record sheet I (Fig. 4) as shown by the second item on the sample sheet. For

this purpose, two orders oi'the printing device and two type bars are associatedwith a pence When the magnet order ofthe accumulator. v RIO is energized by the appearance .of the 'x perforation, the contacts RI5B (Fig. 5A) are closed to effect the entry of an impuhe at the one time in the operation of the machine to cause the tens of pence order of the type bars to print the figure 1. be followed from line 232 (Fig. 5A) through the pence order of the printing magnet PM, contacts I14; plug socket "I, plug wire to socket 313, con-..

tacts RIIB, wire 335, contacts 0P3 clmd at the one index point, wire 33I, wires 315 and 245, and contacts GL2 to line 230. In the lowest order m listing'circuifmay f 25 31I and line 29I.

one cycle later under the lower brushes.

of the printing bank, the figure 0 will be printed since no perforation is sensed through contacts 362 during the rising movement of the lowest order type bar. -Therefore, this type bar will rise to the highest position with the 0 type in line with the printing hammer.

The entry of 11 pence into the accumulator involves an operation somewhat different from the entry of pence. The existence of a per- 10 foration in the R position on the card is sensed as 15 wire 382 and brush 383 because the spot 384 on commutator 385 is timed to make contact as the.

R position is passing the upper brushes. The circuit continues through brush 386, contacts CF5, and contacts R2A to line 290.

The energized magnet RI I closes contacts RI IA and sets up a holding circuit through holding 'magnets RIIH and RI51. The holding circuit includes line 209, wire 369, contacts CFI5, wire 316, contacts RI IA, magnets RI IH and Rl51, wire Magnet RI51 then closes contacts 381 (Fig. 53) to connect the pence order magnet AP to a circuit timed to operate the accumulator gear for a movement of 11 steps.

tacts 359, wire 358, contacts 351, wire 356, contacts 381, wire 386, brush IIA,. commutator segment 389, contact ring 316, brush CA, contacts R6B, wire 311 (Fig. 5A), wire 318, wire 246 and contacts CL2 to line 290.

At the same time that the. value 11 is added in the pence bank, the two lowest order printing banks are operated to print the number 11. To do this, the magnet RI51 opens contacts 362 (Fig.

40 5A), and closes contacts 390 at the same time magnet RI IH closes contacts RI IB. After these connections are made, the closing of contacts CF3 at the one index point directs a pair of im- 45 pulses through plug sockets 363 and 319 energiz- 50 sition on the card may not only indicate the value of 11 pence, but its presence in certain columns, when the machine is plugged for control in subtraction, may indicate that the card carries a credit item which is to be subtracted 55 from other amounts such as debit items carried on cards free from such'special perforations as perforation 2 in Fig. 3.

When the cards are fed through the machine they pass first under the upper brushes and then As the card passes under the upper brushes it is sensed to determine whether it carries a credit item accompanied with a special perforation such as 'the X hole 2. If such a perforation is sensed,

5 certain relays are energized to shift contacts so 70 entered into another accumulator then it is necessary that the accumulator orders be divided into two sections, one to receive the true numbers of credit items and complements of debit items and the other to receive two numbers of debit 75 items and complements of credit items. Such magnet AP, contacts I14, wire 352, wire 360, con-' construction is shown in the copending application of A. W. Mills, Serial No. 634,454, filed Sept. 23. 1932.

In the present case, the accumulator is shown as having only one accumulator designed to add and subtract English currency. It is understood that a pair of such accumulators may be provided to handle simultaneously debit and credit amounts.

The subtraction control circuit is as follows:

from line 292, wire 2I3, common brush 230,- contact roller 23L an upper brush U'B in a column plugged for sensing special perforations,

plug socket 232, a plug wire to socket 39I, magnet XC, contacts CF3, wire 32I, contacts R2A an line 290.

The energized magnet XC closes contacts 234 and sets up a holding circuit through magnets M01 and to magnet XCH. This circuit is from line 269, wire 369, contacts CF22, wire 392, contacts 234, magnets KC and MC1 and line 29I.

The energized magnets M01 operate a series of contacts 244, 245 to deenergize certain relays and energize other relays for the shifting of subtraction control contacts throughout themachine. Normally, the contacts 245 are closed to energize relays R41, R49, RI 23 and RI to control the direction of an adding impulse for the addition of a debit item. An example of a circuit through one of such relays may be followed from 'line 260, through contacts GL2, wire 393, jack 394, plug wire to socket 241, contacts 245 normally closed, socket 248, plug wire to socket 395, magnet R41, bus bar 396, contacts CF26, and wire 31I to line 2III. On the operation of magnet M01, contacts 244 are closed and then the circuit is directed through plug socket 252 and a plug wire to socket 391, magnet R46, bus bar 396, contacts CF26, and wire 31I to line 29I.

By reversing the plugging in certain orders, such as the highest order, in running a plug wire from 252 to 395 and from 248 to 391, a complement may be entered as other orders enter true numbers. For ordinary adding operation the magnet R41 is energized by plugging directly from socket 394 to 395.

Considering first the entry of a complement in the ordinary accumulator banks other than the pence bank and half pounds bank. In these orders, the accumulator magnet A is energized at the 9 index position to start the accumulator wheel revolving. The operation of accumulation continues until the associated magnet SC is energized by the appearance of the perforation at a certain index point in a related column on the card. The differential position of the perforation determines the, complementalvalue of the figure entered.

A circuit for the clutching of the accumulator wheels at the 9 index position may be traced from line 200 (Fig. 5A), contacts GL2, wire 246, wire 318, wire 311 (Fig. 53), contacts CF28 closed at the 9 index position, wire 398, wire 399, contacts RI 22A closed by magnet RI22 during subtraction, contacts PBCA, wire 35I, wire 352, contacts I14, through magnet Ato line 292. This serves to start the accumulator wheel-revolving and the operation of the wheel continues until a perforation is sensed, then a circuit is directed through the related magnet SC (in the present instance the pounds order magnet) for the termination of the complement entry. A circuit may be followed from line 208,- contacts 0L2, wire 246, contacts CF2, common brush 2I9, contact roller 226, lower brush LB, socket 22I, a

plug wire to socket 224, through cable 22! (Fig. 6B) contacts RI2IA closed for subtraction, wire 406, contacts I'll, magnetf SC and line 202.

The entry of a complement in the half pounds 5 or tens of shillings order follows a somewhat similiar course of operation. However, in this order, it is unnecessary to add more than 1 as a complement at any time.' The bank is designed to transfer when amounts larger than one are added in it. Therefore; the related accumulator magnet AH is energized at the one index position for the meshing of the accumulator wheel to start the entry of a unit when a zero is presented in the related column on thecard. The circuit through magnet AH may be followed along a circuit from line 266, contacts CL2, wire 246, wire I16, wire I, contacts CF! closed at the one index position, wire I (Fig. 5B) contacts RI22B, contacts PBCA, wire "I, wire 352, contacts I'll, magnet AI-I to line 202. The circuit terminating the complement entry operation is directed through a' hole in a card to cable 226, contacts R|23A, wirejlll and magnet SC associated with magnet AB in the same manner as described above in connection 25 with the termination of the complement entry in the pounds order. 1

For the entry of a complement in the pence order, the accumulator. magnet is energized at a time corresponding to a twelve index position, in other words, the magnet is energized three index points beforethe regular nine index point position. Thisis done so that a complement of any number of pence from zero to eleven may be entered into the lowest order. The pence complement entry initiating circuit may be followed from line 2I6, c ontacts GL2, wire'2l6, wire 218, wire 31! (Fig. 513), contacts R63, contacts CA, contact ring 316 on commutator 3', a contact spot "2 located on the commutator in a position 2 40 to contact a brush I2A at the i2 index position.

The circuit continues through wire lll, contacts RI24B, wire "I, wire 352, contacts I'll and magnet AP to line 202. The related accumulator wheel is meshed with the driving gears and rotation is started and continued until magnet SC is energized. If SC is energized byany ofthe or- SC in the pence orde .and line 262.

, Should the values '10 or 11 be perforated in the pence column of index' points, it is necessary" to energize magnet SC early in the complement en- 'tering operation. This is done so that the' value 2 which is, the complement of 10 or the value 1 which is the complement of 11 may be added in the pence order. This early energization of SC is taken care of by the sensing of the X'and R perforations under the upper brushes one cycle be- .65 fore the complement operation, just as in the adding operation they were sensedahead of time and in the same way as in adding, the magnets RIO or R are energized according towhether a 10 or 1'1 perforation is sensed. Thecontrol'magnets RI and Rl5l' are oper- -ated selectively to close contacts 312 or 381 to ake connection with commutator 3" in the samemanner as in adding- The only difference being that in subtraction, the contacts 256 "are 76 opened and the contacts 464 are closed so that the special perforations are directed through pence magnet SC instead of magnet AP. In this way, the 10 and i1 impulses are adapted to pass through magnet SC to follow soon after the starting 12 impulse through magnet AP for the entry of the complements 2 or 1 in the pence order.

The printing of amounts during subtraction of the values in the accumulator is similar in operation to the entry of printing impulses during ad-.

dition. In the orders other than thepe'nce order, the printing impulses follow the regular course from the lower brushes through socket I along a plug wire to socket 26f through'contacts I14 and magnet PM. The true credit values perforated in the card are those represented on a record sheet. In the two printing banks associated 'with the pence order, control is again selectively effected through contacts 362 or contacts 390 or RIIIB or RIIB. The printing impulses for the representation of the digits 0 to 9 are directed through contacts 262. The printing of 10 and 11 is controlled by the closureof contacts 390 and RIIB and the closure of III and both RlUB and of RI IB, respectively.

The special perforation'Z (Fig. 3) has a further useunder control of class selection or class elimination. In other words, the appearance of this perforation on the card may be used to control the, machine to eliminate the addition or printing of the amounts represented thereon or to cause amounts .in a plurality of fields on the card to be directed into a single set of printing banks or accumulator orders. For this purpose, the upper brush sensing the column allotted for the reception of the special perforation 2 is conthrough magnet CS, contacts CF8, wire 32L contacts 32A and line 266.

The energized magnet CS closes an associated pair of contacts CSA and CS3 to set up a hold- 310, contacts CSB, magnets MCR and wire fll.

,- taking of totals to select the orders in the accumulator to be connected to the printing magnets for the control of the printing of the balance.
